Baked Spinach Dip Loaf

This is SUCH amazing spinach dip!  I included the recipe as written because it seems fun in the bread bowl.  I just heated it in my crock pot when I made it.

2 pkgs (8 oz each) cream cheese, softened
1 cup mayonnaise
1 10 oz pkg frozen spinach, thawed and squeezed dry
1 cup (4 oz) shredded cheddar
1 can (8 oz) water chestnuts, drained and chopped
5 bacon strips cooked and crumbled
1 green onion, chopped
2 tsp dill weed
1 clove garlic, minced
1/2 tsp season salt
1/8 tsp pepper
1 unsliced round loaf (1 lb) sourdough bread

Beat cream cheese and mayo together.  Stir in the rest of the dip ingredients.  Cut a 1 1/2 inch slice off the top of the bread and set aside.  Carefully hollow out loaf leaving a 1/2 inch shell.  Fill with dip, replace top, wrap in heavy duty foil and place on a cookie sheet.  Bake at 325 for 1 1/4 - 1 1/2 hours, till dip is heated through.  Carefully remove foil and serve with bread cubes (from the center of the loaf) and vegetables.  I served it with pita chips.
